Question about Shoprider SL73 Echo 3 Wheel Scooter ()
It worked fine until today when it started to shake and jolts on reverse and forward. I fully charged the batteries but it only helped with forward. The reverse shakes and jolts.
The result of data corruption that can occur when power is low enough to get interupted by the load of a motor. The above solution it the correct thing to try first/

`Hi. Sounds very much like a loose battery terminal, or a faulty battery lead connector.
I have also had a few machines that can start jerking because of worn or stuck motor brushes.
Also check the high/low speed switch if you have one, they sometimes cause problems.
How old are your batteries, worn out batteries can still be " fully charged", but are unable to supply the current ( amps ), that the motor needs.
Good luck. Neil.

Hi. Sounds to me as if you have a sticky carbon brush in the motor. Each brushe is held in the motor by small black plastic or bakealite cap that screw in the outside or the brush holders. If these caps are not tight enough then the brush or the spring will arc from the side of the brush holder. This causes the brush to become jamed, and does not contact with the commutator on the armature.
You need to remove the brushes, check that they slide freely in the brush holders, fit new springs if neccessary, and reassemble. If the brushes are too tight, the file very carefully on the sides to allow them to move freely. Do not tighten the black plastic caps too hard or they will break, but they have to be snug. Be carefull.
Good luck. Neil.

Testimonial: "This guy is great Sorted out the problem in no time a real genius. Long distance diagnoinics is really hard I know but he got the problems in no time at all"
When you say that you put in a new battery, I hope you mean new batteries. This particular scooter takes 2 batteries and just changing one will leave the remaining one in poor condition. Make sure that you have replaced the batteries with the correct size and type. This scooter takes 2, 40 amp hour batteries. Sealed gel AGM batteries are preferred. The batteries should have the number 40 on them with a date code. You need new, fresh batteries to have them work properly. A date code tag of A1 indicates the A month(1st month) or January of 2011 (1 is for 2011). If you are not sure of the battery condition a local shop can load test them for you.
There is a possibility with a 5 year old scooter that a worn motor/brake will cause excessive current draw and drain your batteries. A qualified technician can determine this for you with a service call.
Hope this helps.

SOURCE: my battery is full charge.when
According to the Owners Manual: Circuit Breaker (Reset Button)
Your scooter is fitted with the latest in electronic controls that are programmed to protect
the electrical system from abnormal overloads. Provided for extra protection is a circuit
breaker, located on the battery pack. Should there be a situation where your scooter stops
for no apparent reason, please check that the circuit breaker has not popped.
If you have misplaced your Owners Manual, here is a link to one. It may not be the exact model you have (as, your Model # was not recognized), but they all work pretty much the same way.
Hope this helps to get you scooting along, again.
